The Med Aire Edge is a dual mode system with Alternating Pressure Therapy with the added safety feature of a 3” wide transfer edge. This helps enable safe and easy transfers on and off the surface, and also reduces falls and entrapment. Alternating modes assist in wound healing and prevention and there are four operating cycles (5/10/15/20 min) based on therapy requirements. The Med Aire Edge also has a Constant Low Pressure (static) option, as well as a max inflate and seat inflation for the Fowler position. A 3” foam layer is also built into the base of the surface to prevent clients from bottoming out. The mattress cover is treated with an antimicrobial to guard against degradation from microorganisms on the cover. The durable cover also tolerates cleaning with disinfectants, refer to user manual for suggested disinfectants.
